EXHAUST GAS PURIFICATION DEVICE FOR MARINE DIESEL ENGINE USING LOW-QUALITY FUEL SUCH AS FUEL OIL CONTAINING HIGH CONCENTRATION OF SULFUR

摘要

Provided is an exhaust gas purification equipment for a marine diesel engine allowing, particularly in exhaust gas treatment of a marine diesel engine using fuel equivalent to or lower than fuel oil in quality, discharge of treated waste water of treated discharge water to the ocean even during sailing in and outside special areas. In the exhaust gas purification equipment for the marine diesel engine using fuel equivalent to or lower than fuel oil in quality, a gas cooler is provided to an exhaust gas route or EGR gas route, an electrostatic cyclone exhaust gas purification equipment is provided on a downstream side of the gas cooler, and a PM-free scrubber that hardly dissolves or removes PM is provided downstream from the electrical precipitation means.
